It is important to emphasize that the key to success, regardless of the clinician's choice of agents, is the prevention of marginal microleakage of the restoration, which could lead to bacterial contamination. In assessing the potential risks of using formocresol clinically, however, it is important to consider the pharmacokinetics of formaldehyde. However, the authors state that the cost of MTA may preclude its routine clinical use. Formocresol has been used in dentistry for over 100 years, and for vital pulpotomy in primary teeth for over 80 years. A case of a deep subgingival fracture treated with a, Journal of Evidence Based Dental Practice. When using FS, the amputated pulps at the canal orifices are wiped with 15.5% solution of FS (Astringedent) for 10 to 15 seconds. Another interesting finding was that gray MTA showed a significantly higher number of dentine bridge formation than white MTA. PC differs from MTA by the absence of bismuth ions and the presence of potassium ions. Tricresol formalin, another formaldehyde preparation, contains 10% tricresol and 90% formaldehyde. Listing a study does not mean it has been evaluated by the U.S. Federal Government. 62,63 Electrosurgery also has demonstrated success. MTA paste is applied to cover the exposed radicular pulp surface with a margin of not less than 1 mm beyond the pulp dentin interface. 0000050707 00000 n Originally, the aim of using formocresol was to completely mummify (fix) all residual pulpal tissue and necrotic material within the root canal. The patient's mother supplied a recent panoramic radiograph that had been recorded by the girl's previous pediatric dentistry specialist (Figure 2). Jeffrey A. 0000030454 00000 n In a preliminary study comparing MTA with formocresol, with follow-ups ranging from 6 to 30 months, none of the MTA-treated teeth showed a clinical or radiographic pathologic process. 0000048074 00000 n A survival analysis demonstrated that the overall probability of survival remained high over time with a cumulative survival of over 95% after six years. However, before routine clinical use of PC can be recommended, further studies with large samples and long follow-up assessments are needed. NaOCl pulpotomies had a 95% clinical … Such signs indicate that the tooth is not a good candidate for, Glutaraldehyde (GA) has been proposed as an alternative to, Problem-Solving Challenges in Dentin Hypersensitivity and Vital Pulp Therapy, James L. Gutmann DDS, Cert Endo, PhD (honoris causa), FACD, FICD, FADI, Paul E. Lovdahl DDS, MSD, FACD, FADI, in, Problem Solving in Endodontics (Fifth Edition). The 1:5 concentration of this formula is prepared by, first, thoroughly mixing three parts of glycerin with one part of distilled water, and then adding four parts of this diluent to one part of Buckley’s formocresol, followed again by thorough mixing. Further studies with longer follow up period is needed to correlate the success rate with the follow up time after providing formocresol pulpotomy therapy. 0000031482 00000 n A recent 18-month follow-up randomized clinical study found similar results when Biodentine was compared with ProRoot MTA.143, Nonpharmacotherapeutic approaches to pulpotomy include the treatment of radicular pulp tissue by electrocautery or laser to eliminate residual infectious processes. They reported a 99.4% success rate (one failure) for this pulpotomy technique. In a preliminary report of the same study, a much lower success rate was described (77.5% for the FS group and 81% for the DFC teeth), with internal resorption evident in five teeth treated with FS and four teeth fixed with DFC.118 This discrepancy can be explained by an excessively severe interpretation of the initial findings. Formocresol has been the medicament of choice for many years and its use is still widespread, mainly because of its high success rate.122 Calcium hydroxide may promote internal root resorption in primary teeth.101 Formocresol presumably fixes affected and/or radicular tissue so that a chronic inflammation replaces an acute inflammation.101, Because of the topical and systemic toxicity of formocresol and the assumption that calcium hydroxide causes internal resorption in primary teeth, other alternative agents and techniques have been suggested and studied.50,79 Numerous agents and techniques have been suggested, including ferric sulfate, glutaraldehyde, bone morphogenetic proteins, electrocautery, and lasers for pulp amputation.50,79,99.
